This paper presents improvements and applications of magnetic frequency tripler which is composed of the bridge-connected reactor circuit reported in the previous papers. [1,2] Generally speaking, a frequency multiplier composed of nonlinear magnetic elements indicates the very difficult conversion operations as this tripler does. In such kind of problems, the numerical analysis of nonlinear equations will not be clarified the physical relations among several parameters. Sometimes it is difficult to solve the relations needed in the design. Therefore, the experimental analysis of each parameter was done in this paper. As the result, quantitative relations between characteristics and circuit constants may be derived. It is possible to clarify the optimum circuit conditions. The new circuit composition with improved characteristics is obtained. Moreover, this paper indicates, as an example of applications, the nine times frequency multiplier composed of two bridge circuits connected in cascade.
